基于项目反应理论的计算机自适应测试算法的研究与实现

摘要

With the continuous development of educational testing theory, computer adaptive test has been widely studied and applied, this paper is based on item response theory, using the three-parameter Logistic model to provide a efficient computerized adaptive testing algorithms, thereby to improve the efficiency and accuracy of the test, and finally achieve the evaluation of the ability of candidates.%随着教育测试理论的不断发展，计算机自适应测试得到了广泛的研究与应用，本文在项目反应理论的基础上，采用三参数Logistic模型进行研究，提出了一种有效的计算机自适应测试算法，从而提高测试的效率和准确性，实现对应试者能力水平的估计。
